Merging (vid+aud) doesn't work

[evolucja]

The following command:

root:~# youtube-dl https://youtube.com/watch?v=j1cL23iJSqg -f 136+140

[ffmpeg] Merging formats into "Tajemnicza przesyłka i tylko 72 godziny-j1cL23iJSqg.mp4"

returns a 804KB file which contains only audio. It also doesn't delete f136 and f140 files but leaves them on server.

It works fine here. Just to verify, you have looked into Tajemnicza przesyłka i tylko 72 godziny-j1cL23iJSqg.mp4, don't you?
Could you post the output of ffmpeg -y -i 'Tajemnicza przesyłka i tylko 72 godziny-j1cL23iJSqg.f136.mp4' -i 'Tajemnicza przesyłka i tylko 72 godziny-j1cL23iJSqg.f140.m4a' -c copy 'Tajemnicza przesyłka i tylko 72 godziny-j1cL23iJSqg.mp4' (or with avconv if you don't have ffmpeg), that's the command youtube-dl runs.

There's already an open issue about removing the dash files: #2108.

By the way, are you really running youtube-dl as root?, if so, I would highly recommend you not doing that.

1. yes I have.

2. how can I create the special user for youtube-dl and use it with Apache on Ubuntu?

Run the command printed in the output of youtube-dl https://youtube.com/watch?v=j1cL23iJSqg -f 136+140 --verbose, in my case it uses ffmpeg, but in ubuntu it probably uses avconv:

[debug] ffmpeg command line: ffmpeg -y -i 'Tajemnicza przesyłka i tylko 72 godziny-j1cL23iJSqg.f136.mp4' -i 'Tajemnicza przesyłka i tylko 72 godziny-j1cL23iJSqg.f140.m4a' -c copy 'Tajemnicza przesyłka i tylko 72 godziny-j1cL23iJSqg.mp4'

[evolucja]

running that command provides:
[debug] ffmpeg command line: avconv -y -i 'Tajemnicza przesyłka i tylko 72 godziny-j1cL23iJSqg.f136.mp4' -i 'Tajemnicza przesyłka i tylko 72 godziny-j1cL23iJSqg.f140.m4a' -c copy 'Tajemnicza przesyłka i tylko 72 godziny-j1cL23iJSqg.mp4'

and when I copy&paste that, I'm getting the same result - 804KB output file with the sound only.

:~#  avconv -y -i 'Tajemnicza przesyłka i tylko 72 godziny-j1cL23iJSqg.f136.mp4' -i 'Tajemnicza przesyłka i tylko 72 godziny-j1cL23iJSqg.    f140.m4a' -c copy 'Tajemnicza przesyłka i tylko 72 godziny-j1cL23iJSqg.mp4'

I see now that the problem is common and i'm not the only one affected by it:
#1809

I tried to update my avconv to 10.1 and it seems working now, however I'm not sure if I did it correctly.. but i hope i won't have problem with it.

I'm closing the issue then, thanks for reporting.
